t would seem all one has to do is take your proven mix and add five more ounces of oil per gallon.
May be misunderstanding but seems like your would be short on oil. (3 gals of standard (gas/glow) mix and 15 oz additional of oil is about 6.9% for oil)
To 132 oz of 80-10-10 (MON) adding 236 oz of gasoline and 26 oz of oil yeilds final mix: Gas 59.9% , Meth 26.8%, Oil 9.9%, Nitro 3.4%.. Which approximates the methonal and nitro of standard g/g mix
